CuraLin Herbal Supplement for Type 2 Diabetes

Stopped early · Not applicable

Conditions studied: Type 2 Diabetes

In brief

The purpose of this study is to provide preliminary data necessary for a larger, controlled trial of CuraLin as a treatment option for T2DM. This study will also fill the gap in literature surrounding herbal medicine in the treatment of T2DM. The use of herbal preparations for diabetes has increased globally, and given the costs, adverse effects, lack of clinical outcome improvement, and minimal A1c reductions associated with medications, safer, more affordable alternatives need to be explored. CuraLin™ is a dietary supplement manufactured by NutraStar Inc. and sold by CuraLife; it is a blend of nine ayurvedic plants and herbs taken three times daily, after meals for the management of diabetes. It is hypothesized that CuraLin will be safely tolerated among adults with Type 2 Diabetes Mellitus, and will improve glucose control and cardiometabolic risk factors over this 12 week study.
